Printing Files with a Forms Overlay on a 3800

Some of the files you print may require a forms overlay. This feature, when active, causes the 3800 to flash an image onto selected pages of a print file through a film negative mounted in a frame. To print files with a forms overlay on a 3800:

1. Choose a group of files that need a forms overlay.
   To do this, enter:

   query printer
   query printer exp

   Under the FLASH heading, find a group of one or more files that have a forms overlay name. For that group of files, also note the CLASS, FORM, DEST, CHARS, and FCB settings you need to enter with the START command.

2. Drain the 3800 by entering:

   drain rdev

   where rdev is the real device number of the printer.
3. Locate the correct film negative and mount it in the frame in the 3800 printer.

   For each forms overlay name, your installation should have a corresponding film negative. If you do not have a film negative for a particular forms overlay name, contact the person at your installation who makes the negatives available for use.

4. Start the 3800 with the correct forms overlay name by entering:

   start rdev flash name other-options

   where:

   rdev

   is the real device number of the 3800.

   name

   is the forms overlay name you want to start.

   other-options

   are the other options you have chosen for the START command.

5. When you receive CP's request to mount the new form, change the paper, if necessary.
6. Enter:

   start rdev

   where rdev is the real device number of the 3800.

The 3800 then starts printing both files that require the specified forms overlay and files that do not require any overlay. The 3800 flashes an image onto print files that require the overlay. Files that do not require an overlay are printed without it. When printing ends, you may repeat the procedure for a new forms overlay name.

start rdev flash off other-options
